Laminated core for rotor of electrical machine e.g. electric motor, has pressure slats and pressure fingers positioned between two metal sheets, where pressure slats are positioned in area between grooves of core

摘要

The core has pressure slats (9) and pressure fingers (11) positioned between two metal sheets (7), where the pressure slats are positioned in an area between grooves (8) of the core such that the pressure slats engage with the metal sheets. Each pressure slat includes a projection for engaging with the metal sheet, where the lengths of the pressure slats are radially aligned, the widths of the pressure slats are tangentially aligned, and the heights of the pressure slats are axial aligned. Each pressure finger includes a circular arc segment.
